Graphics LCD In Proteus

Hello there, you have reached this page because you got a direct link or you were searching about graphics LCD interface / simulation in Proteus. Well this could be one of those right places to look for. Below is a "pretty basic" GLCD simulation as it runs on Proteus. Following are the platform details.

uC - ATMEGA32.
IDE - CodeVision AVR
XTAL - 16 MHz.
No word wrapping.


People interested in code details can leave a comment.
Plus any suggestions on improvement etc :P

Ubuntu on BeagleBoard.....

Finally, got running Ubuntu 10.04 on my BeagleBoard. All setup with a pretty slick script. Two actually - setup_sdcard.sh and the one below:

1. Goto http://elinux.org/BeagleBoardUbuntu#Help
2. Download http://rcn-ee.net/deb/rootfs/ubuntu-10.04-minimal-armel.tar.7z
3. Unpack it - tar -xvf ubuntu-10.04-minimal-armel.tar [after unzipping it in WinRAR or 7z]
4. Run the script - ./setup_sdcard.sh --mmc /dev/sdX --uboot beagle

And bingo after a while the BB boots up with Ubuntu (console version)

I did however try a few things though. Got an Angstrom full development enabled image / rootfs generated by the Angstrom Online Builder utility at http://www.angstrom-distribution.org/narcissus/
This one however did not run on the BB as it was getting stuck at Free init memory 168K which indicated a broken or incorrect build. Now as it had some binaries compiled for the ARM architecture i used the same on Ubuntu. A few worked but the one that i really wanted to - arm-linux-gnueabi-gcc - did not, giving an error saying - execv : Exec format error. However i managed to run vim from Angstrom distro in Ubuntu -

- Copy vim binary from /usr/bin of Angstrom to /usr/bin - of Ubuntu
- Copy all the following libs from /usr/lib - Angstrom to Ubuntu
- libXt.so.6.0.0 as libXt.so.6
- libSM.so.6.0.1 as libSM.so.6
- libICE.so.6.3.0 as libICE.so.6
- libX11.so.6.3.0 as libX11.so.6
- libXau.so.6.0.0 as libXau.so.6
- libXdmcp.so.6.0.0 as libXdmcp.so.6

- Copy everything from /usr/share/vim/vim72 of Angstrom into sams path of Ubuntu.
- Edit vimrc of Ubuntu at /usr/share/vim and comment syntax highlighting, uncomment the indentation related lines and add set backspace=2 to make life easier and prevent any startup warnings.

Bingo, now we've got vim running on ubuntu from angstrom the hard way...
Now only if i could compile stuff directly on the BB !!!
